Abstract :
Describes CACTUS, a two dimensional symbolic compactor that can handle stacking rules, transistors with any shape, long contact plus body-ties. Other features are wire-length minimization, overconstraints relaxation, user-defined constraints, four different types of envelope positioning. CACTUS is internally based on an enhanced virtual grid structure and constraint graphs
